Special objects of the present invention are to improve the counterconstruction of shoes, to facilitate the locating and the placf ing ofthe counter in proper position on the ,5 sole, to enable the securefastening of the counter in place without resorting to nails, tacks orthe like, .to fasten the counter in solid, close fitting engagement withthe sole and upper, and free of ridges or the like over, the top of thesole and to enable the turning of the upper as a part of or continuationof the same counter securing operation; a

' These and other important objects are v 1' attainedin this inventionby the novel features of construction, combinations and relations ofparts hereinafter described and claimed;

The drawings accompanyingand forming part of the specificationillustrate a practical embodiment, of the invention and a commercialform of apparatus for carrying out the method of the invention, but itshould be understood that modifications may as regards these disclosuresall Within the' true spirit and scope of the'invention; j

The counter as possibly best shown in Figs. 1, 2 and 3 consists in thepresent disclosure of an upright tapering wall 10 having a sharplyangled substantially square cornered thick base 11 and above that an inWardly tapering integral attachment flange 12. This counter may beformedas dis closed in Fig. 8 of co-pending application,

'Ser. No. 324,673 Patent 1,711,001,of May 21, 1929, from solid leatherstock by shouldering and splitting the lower thicker edge of the stockand then bending in the flange to leave the base as a heavy squarecornered rib aboutthe rim of the counter projecting below the flange,the latter being rooted directly in the thick heavy body of the counter.a,

To cooperate with this counter, the sole 13 is shown as rabbeted at 14about the edge of the same to provide a substantially angular seat forthe angular base of the counter. The upper 15 is indicated as secured inthe rabbet of the sole by channel stitching 16. This upper maybeconstructed as usual with a back seam at 17 Fig. 9 and advantage istaken of this fact to aid in the proper location of the-counter on thesole. The extra thickness of this seam forms, in effect, a lug l8 intheangle of therabbet, 0.11 the center line of the sole. To fit this lug,there is formed a notch or recess 19 in the inner face of the base ribof the counter, Figs. 1

and, 5. Consequently, the counter may be lulo d ement s-emp yed, h chunde heavy pressure permeates the leather and forms a permanent bond inabout three minutes time. Fig. 4 shows, possibly somewhat exaggerated,howthis cement at'21 applied to the undersideof theflange and the,inside of; the base ribuof the, channel forms a. continuous bondfastening the counter securely and over extensive meeting surfacesto-boththe sole and the upper. This bonding material also enters betweenthe stitched edge of the, upper and the. sole as shown in Fig. 4,soJthat all partsbecome positively connected,

:A suitable clamp oppress maybe emv ployed for elfectingthepermanentconnectionloflthe parts, the means for this purpose being shownin Figs. 6, 7, and 8 as comprising upper andlower press members '22,

23, over a table 24 mounted for rotation by apcst .25. In theillustration, the lower clamp elements 23 arein-the nature of flxed,

anvils shaped tofthe general outline of the counter portion of thesoleand the upper .members 22, shaped to the insideoutline ofthe counter,are carried by spring lifted plungers 26 guided in the headportion 27 ofthe table and adapted to be forced downward by cams 28 controlled byhandles 29, said cams bearing on the upper ends of the plungers at 30.These cams, are shown shaped and located so as to hold the clampsclosedwhen turned down'to'the position indicated at the right in Fig. 7.In the machine shown there. are six clamps on .the

rotatingtable. ,This numberallowsa sufiicient time intervahfor thecement and the secured portions to become permanently welded together. Aspring pressed trip lever is'indicated at 3l jfor holding the tablelined up, each time witl1' ,a. clamp innfront of the operator. In theillustration, the

operators station may be supposed to be in front ofth'e o'pen clamp atthe left in Fig.;7.

. was the clamp open as shown, the sole,

With the upper reversed is hooked over the anvil piece "and while heldthis. relation,

the counter is slipped into position oyer the .sole and centered on thesame by themgagement of the notchover the seam lug.

'The adhesive cement or; bonding medium having been previously -app'liedwithin the angle of the counter beneath thesecuring flange, or about,the,rabbeted;edge portions h herei w ad er .meme tar 1y while the clampis being closed, or a foot treadle or power means may be provided forclosing the clamp while the parts are thus held in assembled relation.The upper clamp member isshaped to the desired final outline of thecounter, so that when pressure is applied as in Figs. 2and3, it pressesthe flange ofthe counterfirmly down over the sole and the foot of thecounter firmly into the rabbet of the sole, this pressure beingsuflicient to, close. upeany spacesxandebring' the contacting portionsof the counter, sole and upper into a substantially solid mass as shownin Fig. 4:. The clamps preferably are allowed to "remain closed over thefull revolution of the table, .or a. sufficientperiod to enable thecement and the penetrated portions-ofjthe parts to dryand harden .thispractically solid mass. ,Under this heavy pressure, the taperedsecurlngflange may be flattened down into the body Ofthe sole substantially asindicated inv Fig, 4. This leavesa substantially flat surface inside theshoe over which the shank stiffener or insole will lie flat andfreeofany bumps-,

or ridges.

Before removal from, the clamps, the. partially completed shoes may beturnedlf from the reversed relation shown atthe, rightfin Fig.7 tothe.condition shown. in Fig. ,8-

wherejthe u per has been,pulle d up over the top inemgerofjthe clamp.The turning of the shoes while so held'in the clamps is ofspecialfadvantage. astheshoes are so 'firmly andpositively heldat thetime. :Also;

under these conditions, all strains-v are borne by the clamps. which,are. then. still holdingthe freshly securedpants together. Thus,-eventhough the. shoe. be turned before the adhesive has finally set, vnoharm canresult because at such time theparts will still be positivelyheld together by the clamp.

The interlocking of the, counter -in .,practically solid relation.withthe rabbeted sole and the fastening of the. parts in this.relation, under pressure,.with ,a. permanentQcement, makes the counterpractically .an.integral part of the sole,- eliminating theneed for,tacks; or other, fastenings heretofore used. This is a greatadvantage,,saving time andlabon and avoidingany lumps or irregularitiessuch as are usually i left where tacks or similamfa stenings areemployed forsecuring the counter.. By,using thepenetrating cement,interlocking, the partsin solidly fitting relation and forcingthe.parts-. of.the'

counter intotheesoleand holding them until the cement has set continuouspermanent bondis effected, between the tmeeting surfaces. and the parts,are inefl'ect fused together, in aE solid integral, .mass. .1 This:continuousffusion. 'or welding of the -;counter to-thegsoleinadditioneto. avoiding .the need gfor nailing the, counter. in\ place,.prov des a tronger, better. fitting and 'better Thus the parts arepermanently secured together with a strength practically equal to v oras great as the strength ofthe separate parts. The counter thusstrengthens'and reinforces the sole and similarly the sole gives itsstrength to the counter.

This unification of the counter and sole is of benefit also in thesubsequent heeling operation when the feather of the rabbeted sole istrimmed awayto receive the heel as the parts are so firmly braced andconnected that the trimming can be quickly and easily effected andwithout any loosening of the pressed fit connection between the parts.
